This Case Study introduces the work undertaken at St George

Wharf to apply best practice to a reinforced concrete flat slab

frame construction project.

The following topics for innovation were investigated and the detailsof the experiences and the benefits achieved under site conditionsfrom applying these ideas are reported in a series of companiondocuments (see back cover) as follows:

Early age concrete strength assessment Early age construction loading

Reinforcement rationalisation and supply

Slab deflections

Special concretes

These are underpinned by reports (see References) giving background and

further information on the innovations.

The work has led to a better understanding and clearer identification of the

issues and constraints to improvements in flat slab construction.

St George Wharf Case Study

The European Concrete Building Projectat Cardington was a joint initiative aimedat improving the performance of theconcrete frame industry. It led to thepreparation of a series of Best PracticeGuides, giving recommendations forimproving the process of constructing in-situ concrete frame buildings.

As part of a programme to disseminateand apply what has been learnt fromCardington, BRE has subsequentlyworked directly with those involved in

St George Wharf, a high-profile, mixed-use, phased project on the River Thames.

BRE worked jointly with the developers,St George (South London), theirengineers, White Young Green,and specialist concrete contractors,Stephenson, to develop and implementprocess improvements tailored to theSt George Wharf site.

This work has led to a series ofinnovations being trialled, the results ofwhich are summarised in this series ofBest Practice Case Studies.
